This cooling plate is slotfor 4 thethrough,.an d is provided with a passa e h extending around the slot andconnecte at the end with a water supply pipe h, and a drainage pipe h,by means of which water or other fcooling fluid' may he flowedcontinuously through the plate in order to keep the same at a lowtemperature.

. Under ordinary circumstances, it will be suflicient to make the plateof a size substantiallycorresponding to that of the mold, but it may beenlarged or extended in the'path of ,the'r'nold to any desired extent'inorder to prolong the period of contact.

' The plate, if properly cooled, will rapidly absorb heat from the moldand exert a marked influence, preventing the over-heatin'gl ortheirregular heating of the mold. In at er words, it will tend,to keep thetemperature of themold within such limits as to prevent excessiveorirregular expansion.

The essence of the invention lies in combiningwith the mold, whateverits form, and without regard to the manner in which it is supported orcarried, an external cooling body of any suitable form adapted tocontact with the mold.

, It is to be obseryed'that the fluid passages 5 shown herein areclosed,or in other words,

are without joints or openings of any kind adjacent to the mold. hispermits of the use of water or other cooling -li uid, as a coolinggrnedium without" danger of leakage into the '5? fnold, where itspresence would be attended thf'flisastrous results on the admission ofthe mol-tea meta -When a r orfother gaseous medium is em- Passing now tomy improvement, H repreassage-of the ejector thereployed for coolinpurposes, small openings may be made in t e plate G to permit the air toesca e and contact with the mold, but under or inary conditions this isnot recommended. I

It is to be observed that the cooling means which I have rovided form nopart of the gold, but are istinct and independent there- The coolingmedium does not enter the mold, and there are no movable joints oropenings through which the water can, bv any possibility, reach thesurfaces with whic the molten metal contacts.

Having described my invention, what I claim is 1. In a linot e machine,a mold in combination with an independent cooling body ar ranged tocontact therewith.

2. In a linotype machine, a slotted mold, an independent cooling body,and means for carrying the mold into and out of contact with said body.

3. In a linotype machine, a slotted mold in combination with anindependent coolin body arranged to contact therewith, an

means for artificially cooling said body.

4. In a linotype machine, the combination of a slotted mold, itsrevoluble supporting disc, and a fixed cooling plate or body Hindependent of the mold proper and arranged to contact with the rearface of the mold.

5. In a linotype machine, a slotted mold, its rotary supportin disc,aslidd sup the disc, and a mo d-cooling bod from the mold carried withsaid sli e.

6. In a linotype machine, the combination istinct orting of a slottedmold and an independent external I cooling bodyarran ed to contact withthe rear face of the mol said bod being slotted for the passage of theejector t 'erethrough.

7. The combination of the mold A, the rotarydisc B supporting the same,and the nonrotating cooling body H distinct from the mold arranged tocontact with the rear face of the disc. In testimony whereof I hereuntoset my hand this thirty first day of October, '1906, in the presence oftwo attesting witnesses.
